vs
Spark plug Autolite or Motorcraft
Reviews
If its just painted like some cheap plugs such as some autolites then yes its needed.
Pros: needed for painted plugs
Cons: not needed if coated
So here is my experience with gaps on this engine. The wife 09 Passat was misfiring so I decide to replace the plugs. I buy Autolite double platinums which were gapped huge. Turns out the 0.032 gap was not correct after all and it should have been 0.028. Big difference, this baby flies again (GIAC tune).
Pros: baby flies again
Cons: misfiring, gapped huge
Vehicle:
Volkswagen Passat
I changed the spark plugs to Autolite Double Plat plugs from Autozone. The smoke cleared up and it is MUCH easier to keep cranked in the cold (30's F) in the morning. It still has a very light stumble every few cycles and a louder engine idle than I'd like, but runs good and seems to be much better.
Pros: smoke cleared, easier cold crank, runs good
Cons: light stumble, louder idle
Vehicle:
Volkswagen Passat B6
I got a Ford, so I use Motorcraft. They work great.
Pros: they work great
Vehicle:
Ford
Autolites last as long for me as the NGK's. Either of them last about 10k miles for me. Any longer than that and I start getting missfires. The Autolites can be found for about $1.00 each
Pros: last 10k miles, cheap
Cons: misfires after 10k miles
Mileage: 10000 km
My dad just returned a set of autolites. I installed them and had immediate misfire.
Pros: easy to install
Cons: immediate misfire
Once we got a good local supplier for Motorcraft plugs a few years ago we almost never install Autolite.
Pros: good local supplier
Cons: almost never install
There seems to have been quality issues with those for quite a while. I couldn't count how many times we removed fairly new Autolite spark plugs and replaced them with a better brand to fix a misfire.
Pros: fixes misfire
Cons: quality issues
I wouldn’t put autolite plugs even in my lawnmower. NGK or Denso only.
Do not get Autolite, I've seen them cause trouble and issues in Honda engines.
Cons: cause trouble, issues
Vehicle:
Honda
